Flickering during Raw video.
« on: June 10, 2013, 12:50:10 PM »
Apologies if this has already been raised, but searching for anything relating to 'flickering' just brings up timelapse/HDR related issues.

I shot my first Raw video on Friday, here's the result -

You can see on a few sequences there's a flickering that seems to be influenced by light in most cases. I can't think of any camera settings that would have caused this, but don't see anyone else reporting this on the June 5th build I used.

5D mkIII - Komputerbay 64GB 1000X - June 5th ML Build - 23.976 fps override - 1920 x 720 - varying ISOs.

If there's something I am missing on-camera, or a process I should be adding to my workflow - Any suggestions welcome!

I think this is because you probably converted this with ACR and used shadow / highlight recovery. ACR is not made for video and those settings somwhow depend on the image content.

I think it's just some auto settings so ACR does what it seemed to him more correct. so it shifts the luma.

Nice work catnip. I don't see the flickering that I'm experiencing in my export. Please take a look at this clip here and help me help myself. TIF 4k Footage from Magic Lantern:
